Abstract

Background: The relationship between calcium intake and obesity is controversial. The aim of this study was to examine whether daily dietary calcium intake has any effect on obesity or metabolic syndrome among middle-aged and older Korean population. Methods: Data of 836 healthy subjects from ages 40 to 60, who had visited the Health Promotion Center in Ajou University Hospital since March 2006 to April 2007, were analyzed in this cross sectional study. The daily dietary calcium intake of each subject was evaluated by 24-hour recall method. Results: Obesity was defined as body mass index ${\geq}$ 25 $kg/m^2$. Multiple logistic regression models were used to estimate the multivariate odds ratios (OR) of being obese in terms of different levels of daily dietary calcium intake. Results: Obese women who were in their 50's had a lower intake of daily dietary calcium compared to the non-obese (obese vs non-obese; $672.19{\pm}240.64$ mg vs $776.11{\pm}213.59$ mg, P = 0.016) women. The Odds ratio of being obese at the lowest quartile of daily dietary calcium intake was 4.82 (P = 0.016, 95% CI 1.49-19.43) compared to the highest quartiles even after adjustment for age and daily total calorie intake. However, no relationship was noted between daily dietary calcium intake and metabolic syndrome. In men, neither metabolic syndrome nor obesity was significantly associated with dietary daily calcium intake. Conclusion: Daily dietary calcium intake was associated with the prevalence of obesity in middle-aged women, especially in their 50's.

연구배경: 칼슘 섭취와 비만의 관계는 명확히 밝혀지지 않고 있다. 따라서 본 연구는 한국 중년 인구 및 노년 인구에 있어, 하루에 섭취하는 칼슘의 양이 비만 및 대사증후군과 어떤 관계를 가지고 있는지에 대하여 알아보았다. 방법: 2007년 3월부터 2007년 4월까지 아주대학교병원 건강증진센터를 방문한 40대에서 60대 사이의 건강한 일반인 836명을 대상으로 단면연구를 하였다. 하루 칼슘 섭취량은 24시간 회상법을 통하여 계산하였다. 비만은 체질량지수 25 $kg/m^2$ 이상으로 정의하였다. 칼슘 섭취량 차이에 따른 비만의 위험도는 다중 회귀 분석법을 통하여 알아보았다. 결과: 50대 여성에 있어서 비만한 여성의 경우는 비만하지 않은 여성에 비하여 하루 칼슘 섭취량이 낮은 것으로 나타났다(비만한 여성 vs. 비만하지 않은 여성; $672.19{\pm}240.64$ mg vs $776.11{\pm}213.59$ mg, P = 0.016). 결론: 하루 칼슘 섭취량을 사분위수로 나누어 비교하였을 때, 가장 칼슘 섭취량이 낮은 군에서는 칼슘 섭취량이 많은 군에 비하여 나이와 하루 중 섭취한 총 열량을 보정한 비만의 위험도가 4.82 (95% CI 1.49-19.43, P = 0.016)였다. 한편 하루 칼슘 섭취량과 대사증후군 간에는 상관성을 보이지 않았다. 남성의 경우는 비만과 대사증후군 모두 하루 칼슘 섭취량과 유의한 상관성을 보이지 않았다. 결론: 하루 칼슘 섭취량은 50대 중년 여성에서 비만의 유병률과 관계가 있다.
